DataStax OpsCenter - managing large
clusters
Managing a large Cassandra cluster can be a pain in the neck with installations over hun-
dreds of machines and across multiple data centers comprising test, staging, prod, and other
environments with multiple keyspaces running on virtual machines with a cloud providers'
hardware getting compromised more often than you would expect. Fortunately, people at
DataStax have built OpsCenter.
OpsCenter is a web application that takes care of all operation-related tasks from a user-
friendly user interface. It smartly uses Cassandra's JMX calls and operations commands to
perform the task. On top of this, you can use it to monitor alerts, performance reviews, and
diagnosis. We will see OpsCenter in more detail in the next chapter.
For a small cluster setup (say, under 25 nodes), it is may be simpler to stick with simple
automation based on
nodetool
and perhaps shell or Python script. It will keep the ad-
ministration simple.
